Exec bash shell via PHP Site !
Hi everybody !
I writed php code so exec bash shell via php (SMS Send via bash shell) but i have problem as follow :
1. When i exec from linux mode : ./sms.sh --- output is "Messages ... OK". Then all message has been sent.
2. When i exec from PHP site --- return value is "Message ... OK" on PHP site. But no messages has sent.
I don't know why! This is sample code :
[index.php]
<?php
$output = shell_exec('./bash.sh');
echo "<pre>$output</pre>";
echo "Messages ...OK<br>";
?>
[bash.sh]
#!/bin/sh
### SMS sending code ###...
echo "Messages ...OK"
Anybody can give any ideas in this case !
Thank so much !

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
